COMPOSITE GLUTINOUS ARTICLE AND PROCESS OF MAKING SAME.

This pressure serves also to intimately unite the compoundwith the fabric whether it be applied as a solution or in sheet form,and it serves to condense the compound and give to it the desiredsmoothness of surface and renders it less permeable to water.

The composite sheets made up of the compound and fabric may be separatedfrom each other by strips or sheets of metal, as shown at a.

The press, with the material held therein under the desired pressure, isplacedv in an oven in order to be heated.

I claim 1. The herein-described process consisting in applying aglutinous compound to a fabric and then subjecting the same to a dryingtemperature while under pressure.

2. The herein-described process consisting in applying a compound ofgluten and glycerin to a fabric and then subjecting the same to a dryingtem perature while under pressure.

3. The herein-described process consisting in making a glutinouscompound in sheet form and then applying the same under pressure to afabric and exposing it to a drying temperature.

4:. The herein-described process consisting in making a compound ofgluten, glycerin and a body material into sheet form, applying the sameto a fabric, under pressure, and then exposing it to a dryingtemperature.

5. The herein-described article consisting of a glutinous compound insheet form combined with a fabric,substantially as described.

In testimony whereof I aflix my signature in presence of two Witnesses.

WILLIAM PAINTER.
